Organic light emitting diode display device with a blocking member

Abstract

An organic light emitting diode (OLED) display panel and a display device are provided. The OLED display panel includes a light emitting functional layer and a display area disposed on a transistor array substrate. The reinforcement layer is formed on a surface of a bending area of the transistor array substrate. A blocking member is formed on a surface of the transistor array substrate and located between the reinforcement layer and the light emitting functional layer. By providing the blocking member, the control accuracy of the amount of glue overflow in the bending area is improved.
